zBoost SOHO boosts up to 2,500 square feet. It is ideal for small homes and buildings. It includes omni external antenna CANT-0033, omni internal antenna CANT-0034, and RG-6 cable.

Set-up requirements and instructions necessary for maximum performance:

  1. The outdoor external antenna and indoor rebroadcasting antenna need to be at least 15 vertical feet from each other.
  2. Less than 15 vertical feet of distance between the two antennas will result in decreased performance.
  3. Increasing the distance will increase the performance of the zBoost ZB545.
  4. The maximum distance between the antenna should not exceed 40 feet.
  5. The outdoor external antenna needs to be at least 3 feet above any metal.

Step 1: Mount the external antenna.

  1. Choose a location based on your mobile devices’ signal strength.
  2. Choose an area with the best signal strength.
  3. If the external antenna is place in an outdoor area that receives low signal strength the indoor signal will not be strong and coverage area will be diminished.

Step 2: Mount the indoor rebroadcasting antenna.

  1. Place the indoor rebroadcasting antenna where you want to create increased signal strength.
  2. For the widest possible signal strength coverage place the indoor rebroadcasting antenna in the middle of a room.
  3. The signal broadcasted from the antenna is omnidirectional allowing the unit to be mounted on a vertical wall or placed horizontally.
  4. Do not place the unit on the floor or near other cords, metal, or other wireless devices.
  5. The indoor rebroadcasting antenna features a detachable base unit that can be mounted with screws (screws not included).

Step 3: Connect the external and internal antenna with the provided white coaxial cable.

  1. Run the cable from the external antenna to the indoor rebroadcasting antenna through a window.
  2. Coaxial cable extensions are available in 15 foot lengths (Part: YX030-15W).
  3. Coaxial cable exceeding 65 feet in length is not recommended.
  4. An 8-inch window entry cable is available for purchase (Part: YX030-08W).

Step 4: Connect power supply to the internal rebroadcasting antenna and check system operation.

  1. Plug the power supply into the internal rebroadcasting antenna.
  2. Plug the power supply into a wall power outlet.
  3. After initial power up the LED light will cycle red, green, and orange for 30 seconds.
  4. After the LED light cycles for 30 seconds, the LED will flash green to indicate the strength of the signal, and then will be followed by a solid green light.
  5. If a solid green LED light is not observed refer to the “Base Unit LED Indicators” section of the user manual for further instruction.
  6. Adjustments may be required to optimize the performance.
  7. Check that the zBoost system is in place and fully connected through your coverage zone.
  8. If increased signal strength is observed on mobile devices the unit is working.
  9. Signal strength can be affected by outdoor signal level, building construction, and antenna placement.
  10. Coverage can be reduced by interior walls and ceilings.

Step 5: Enjoy increased cellular signal strength in your home or business!

Questions & Answers


Ask a Question
  • Is this device for ATT cell phones or for all cell phones?

    It is for all 3G cell phones using PCS 1900 MHz band of all cellular service providers in USA & Canada and covers up to 2500 sq. ft. of indoor space.

    However, unfortunately, it is currently not available for atleast a week so we suggest another indoor cell phone signal booster (weBoost Home 4G) which only covers up to 1500 square feet and costs a bit more - but the suggested replacement signal booster will work for all USA & Canadian carriers AND bands on 3G, 4G, as well as LTE networks.

    Furthermore, the suggested signal amplifier kit is plug and play which means that it does not require you to install an antenna outside the house. Its antenna can be mounted on window from inside the house. Therefore, it is easier to install than zBoost SOHO ZB545.

  • I bought your product and it's great!!! However someone broke the antenna. Can you just buy the antenna?

    The antenna for the ZB-545 booster has been discontinued. You can use this antenna now: and it will work for you. 

  • I bought a Zboost about 4 years ago and work it on an island on Lake Superior. All worked well until this spring when I lost reception. I have checked connections, phoned supplier TBay Tel and discussed their tower and also talked with supplier Thunder Bay Communications. No luck yet. When I go up on the roof near the Yagee antennae it works ok. You mention Manual - I don`t have one. Light is green on unit. Wife said it was red one day.

    Have you made any change to the distance between outside antenna and inside antenna? If yes, you may need to distance them again to prevent oscillation which causes that red light and reduction in output power. If not, maybe you have changed your phone to 4G from a 3G phone you had before? This booster is 3G and will not boost 4G reception. What you can try to do is force the phone to go into 3G mode: Go to Settings > Cellular > Cellular Data Options > Enable LTE > Select Off. This will force your phone to use 3G network. Once it does this, check to see signal strength (in Decibels (dB), which is most accurate than the signal bars method) with signal booster turned on. If it has good signal strength, it means you can use this method or buy a new "4G signal booster". Call us if you need any help finding one that will meet your needs and budget.

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

For non installation-included kits: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
